| Posted: 25 Aug 2019 07:45 AM PDT I'm replacing some equipment in my network rack. The router has SFP+ ports, and my switch has SFP. I'm fairly unversed on fiber connections and compatibilities. With this pose a problem or will this work? I know it would run at 1 Gbps and not 10Gbps. What modules and fiber will I need exactly? [link] [comments]  |
| ISP with odd "blackhole" issue. Posted: 25 Aug 2019 03:17 AM PDT Hi all, I'm a shiny new Network Engineer though have a decent amount of background in IT and Networking. Earlier this year I started work at an ISP and everything was running smoothly. I was handed an issue about a month ago where traffic seems to mysteriously vanish for (as far as I can tell) all of our IP ranges, as if our AS is being rejected somewhere. This only happens to certain destinations, though there is no pattern between the route, dest. AS, dest. IP, or Transit used. We managed to resolve this for one destination network by peering with them directly at LINX. What would you guys check here? So far I've attempted reaching out to the NOCs on the destination networks and seeing if they can contact their upstreams, but that's not yielded a lot of return and I'm unsure how else I can investigate this since it's outside of our network. Look forward to hearing from you all. Edit: Just thought I'd add - we're not on any blacklists per my exhaustive checks. I've probably checked a good 100 or so at least. Additionally we have had issues with IP Geolocation, where we're showing up as being in the Netherlands, but I don't see how this could prevent some customers for playing games, for example. We're in the UK. [link] [comments]  |
| Cisco WLC - FlexConnect/CAPWAP through ASA (Firewall Rules required) Posted: 25 Aug 2019 08:00 AM PDT Howdy, I'm trying to setup a vWLC to sit behind a vASA using CAPWAP/FlexConnect AP's and only allow required ports inbound to the WLC (https://i.imgur.com/55bIOn0.png). I'm referring the the document here: However, when I lab this up - I can see the ports inbound using random UDP ports (the random one associated to each AP I assume). The only way I can get it to work is to allow the following: UDP Ports 1024 - 65535 Is this right? Is there any other tidy ASA rule(s) than just allowing the UDP ports above else I get the below: Has anybody had any previous experience of this before? Thanks. [link] [comments]  |

| Recommend edge/switch/WAPs distributed small office Posted: 25 Aug 2019 01:47 PM PDT First post here. We're a small TV/Film post-production group. We've been getting by with SoHo and consumer hardware, but I think we need to invest in some more enterprise-level infrastructure now for reasons of security, performance, and ease of management. I've read about many different brands and others' posted opinions, and it all leaves my head spinning. I'm trying to find what is right for us. I realize there's a ton of "what do you recommend" posts already, but I feel like none of them quite fit our situation. I'll probably reveal how little I know with this post, but I've gone about as far as reading can take me without some human help. BackgroundWe work with intellectual property, so I've always been worried that our security isn't robust enough. Besides that, we're now adding some remote workers in other cities, and so we need to extend an always-on VPN to them with good performance and not compromise security in doing so. We also have team members traveling more, so want to have a good VPN solution they can take with them on the road. Additionally, our customers have urged us to give them on-demand access to client data so they can help themselves to it, which would likely take the form of a self-hosted solution like NextCloud on premises, or else mirroring data to something like Backblaze. We're self-supporting power users without an IT staff. I'm the savviest, with a background in IT as it was my first career (but from a long time ago - I've devolved into a glorified power user now). So it falls to me to design/build/deploy/maintain whatever our solution is. There's also a ton of reluctance to move away from this low overhead model, so costly integrators, support contracts, subscription fees, etc., are not likely to get a consensus nod. I know all the arguments about what our downtime is worth, etc., but I'm not the one to convince on that front. Our group is willing to make some up-front investment, but strongly dislike the commitment of ongoing fees unless it's something very modest (a few hundred a year is OK, but they are not going to spend thousands). Current SetupMain Office
Remote Office (#1 and #2, both the same)
What do we need?I'm looking for a recommendation of the whole stack. The main edge device, the switches and WAPs, the remote Edge device / switch / WAP, whatever kit we might take with us while traveling and working remote (unless it's a software-only solution), etc. I'm OK throwing out what we've got, if that makes sense. My "dream" solution, as far as I can determine, would be something like this:
Notions and PreconceptionsI have ideas, not sure if they're misguided.
Am I asking for the moon, or is there a product stack that would elegantly accomplish all this without breaking the bank / incurring high subscription fees?[link] [comments]  |
| Posted: 25 Aug 2019 02:04 PM PDT Just as the title says. I've tried disabling my firewall and all antiviruses, flushing my DNS, releasing/renewing IPconfig, creating a new Windows user specifically for work, uninstalling/reinstalling Cisco...literally everything. The IT guys at my office can't figure it out either. I also cannot connect to my office's Remote Desktop. For what it's worth, I could work remotely without issue (and connect to both intranet sites and the Remote Desktop) for literal years; then, starting in early February, it just...stopped. I can still connect with my phone, my tablet, and different computer, so it has to be something specific to my machine. Does anyone have any ideas? [link] [comments]  |
| Posted: 24 Aug 2019 04:08 PM PDT Networking has not been a strong point of mine over the years. I've primarily been a desktop tech / Jr. Sysadmin in companies that had separate, dedicated network engineers or teams. I've got the fundamentals of stuff from server, like DHCP, general IP subnetting, DNS, etc. But I recently took a new job at a colo/cloud company that is tons of networking and I'm feeling a bit out of my depth. I'm going to be working with firewalls (Cisco and Fortinet), VLANs on said devices, network load balancing, bgp, VPNs, edge routing, router HA, and much more, and this stuff is all way outside my scope of knowledge. The company knows I don't have all this knowledge, and I was up front about that (my current strengths lie more in the Windows/Linux/VMWare support and management end of things), but I'm doing a lot of training and will have to pick all this stuff up. What are some good resources (books, videos, courses, whatever) I should pick up to get a better grasp on this stuff from the colocation/cloud/ISP end of things, and broaden my perspective on networking and how the internet as a whole works?

| How does an ISP run cable drops to multiple buildings from one line. Posted: 24 Aug 2019 08:28 PM PDT I want as detailed as possible because I can't wrap my head around it. How do ISP's have multiple drops off one wire, I just can't wrap my head around it. Me and a buddy are curious about becoming an ISP and we still have a long way to go, but for the life of me, this is the one thing I don't understand... Like i'm genuinely curious how it actually works. We were going to start as a WISP to get more knowledge as we go, but this is the only thing that stumps me.. [link] [comments]  |
